Draw a BPMN model for each of the following processes described below. Take into account that they will be used as a reusable sub-process. 1) Handling downpayments. The process for handling downpayments starts when a request for payment has been approved. It involves entering the downpayment request into the system, the automatic subsequent payment, emission of the direct invoice and the clearance of the vendor line items. The clearing of the vendor line items can result in a debit or credit balance. In case of debit balance, the arrears are processed, otherwise the remaining balance is paid. 2) Assessing credit risks. When a new credit request is received, the risk is assessed. If the risk is above a threshold, an advanced risk assessment needs to be carried out, otherwise a simple risk assessment will suffice. Once the assessment has been completed, the customer is notified with the result of the assessment and meantime the disbursement is organized. For simplicity, assume that the result of an assessment is always positive.
